You must be very careful when driving in bad weather. You should pay special attention to safety when driving in fog. How to use the light is also very important. Let's explain the principle of using the light in fog, and remember it.
Safety principle 1: correct use of lights
When driving in fog, you'd better turn on all kinds of lights on (except for the high beam lights), which can remind the vehicles behind you of your position. If driving on the highway or when the fog is very thick, turn on the double flashing lights.
Don't use the high beam in foggy days, because the high beam is shining upward. The light emitted is diffusely reflected by the fog, which will form a white area in front of the car. When driving, nothing can be seen.
Safety principle 2: keep a relatively low speed
When driving in fog, strictly abide by the traffic rules and speed limit. Never drive fast. The greater the fog, the shorter the visible distance, and the lower the speed must be. When the visibility is less than 200m and more than 100m, the speed shall not exceed 60km / h; when the visibility is less than 100m and more than 50m, the speed shall not exceed 40km / h; when the visibility is less than 30m, the speed shall be controlled below 20km / h; if the visibility is less than 10m, it is recommended to stop at the roadside, and pay attention to find an absolutely safe place to stop.
Safety principle 3: use the horn to prompt
If it's normal driving, it's not only annoying but also impolite to honk the horn, but it's necessary to honk the horn in fog. This can remind pedestrians on the road that there is a car coming, and pay attention to avoid.
Safety principle 4: do not overtake blindly / pay attention to pedestrians on the road
If you find that the vehicle ahead is parked on the right side, do not overtake blindly, because it is likely that it is waiting for the opposite vehicle to pass. When overtaking the parked vehicles on the roadside, after confirming that they have no intention to start and there is no coming vehicle on the opposite side, honk the horn in time to bypass from the left side at a low speed.
In addition, it is not allowed to drive on the line in foggy days, otherwise there will be a risk of collision with the opposite vehicle. When driving on curves and slopes, slow down in advance to avoid shifting, stopping or flameout.
When driving in fog with poor visibility, pay special attention to pedestrians on the road, especially pedestrians and cyclists when driving in suburbs without street lights.
It's very important to follow when the visibility is below 20 meters in fog. Don't start as the first car. It's better to follow a large cargo. It's about 10 meters away. He's fast and you're fast. He's slow and you're slow. Just see his tail light. In October, I drove for tens of kilometers under the visibility of 10 meters. That's how I drove. I still followed
Safety Principle 5: do not slam on the brake
Don't slam on the brakes because you can't tell the distance between cars in fog. If you slam on the brakes, it will make the rear car unable to judge the distance and cause rear end collision. Of course, the best way to avoid emergency braking is to slow down and have a long distance from the car in front.
If emergency braking is needed in front of you, you can gently press the brake several times in succession to control the vehicle speed and effectively remind the car behind you.
Safety Principle 6: two lanes should be outside and three lanes should be in the middle.
In foggy days, the line of sight is poor, so when driving, if it's one-way three lanes, it's better to drive in the middle of the road rather than on both sides of the road. Because of the low visibility at this time, it is not easy to deal with any situation on both sides of the road. So it's better to drive in the middle of the road.
If it is one-way two lanes, it is necessary to drive slowly in the outer lane. When the vision is poor, the most important thing is to drive slowly.
Safety principle 7: in case of emergency, double flash must be turned on and warning signs shall be set up.
When a traffic accident occurs in fog, the most important thing is not to call the police first, but to design warning signs at the back of the car. Because of the poor visibility, you need to set up the warning signs a little further (& gt; 100m) to ensure that the vehicles behind can evade earlier. After the warning signs are set up, all kinds of lights of the vehicle shall be turned on, especially the double flashing lights, to prompt the rear vehicles. After the warning, the personnel on the vehicle shall evacuate to a safe place immediately and give an alarm at the same time. Do not stay in the vehicle or walk in the lane to avoid secondary accidents.
Safety principle 8: use all equipment to get rid of the fog in the car
I don't know if you have noticed. As soon as there is fog production outside, there is also fog in the car. Therefore, it's better to turn on the rear window defog and rear-view mirror defog functions when they are formed, and turn the air outlet towards the front windshield, and use all methods to reduce the generation of fog in the car.
Safety principle 9: driving in a strange place can rely on GPS
It happens that you are driving in a strange place, and there is a thick fog at this time. What should you do if you can't find the road? At this time, you have a set of navigator is the best. After all, the road information exists in it. You set the route and move slowly according to its prompts. If you can't see the sign in time, GPS will remind you when to drive out of the road, at least you won't get lost.
Conclusion:
Please remember these 9 points when driving in foggy days, and these 9 points are summed up with the word "slow". Foggy days cause our poor vision when driving, and we can't always bring infrared night vision when driving, so please slow down for our driving safety.
